According to a Reuters article at Yahoo News, President Obama is pressured to "do something" about Syria inasmuch as someone, probably the government, may have used chemical weapons. I hope he can resist the pressure, we don't have a dog in that fight.
Assad is an ugly thug, an ally of Hezbollah, Iran and Russia. The opposition is heavily infiltrated by al Qaeda and Sunni jihadists generally. Both sides really hate the U.S.
If the enemy of my enemy is my friend, we should help both sides. Better yet, help neither.
Mr. President, please stay out of Syria; we are not the world's policeman. This is an issue for the United Nations Security Council to ponder, preferably at great length and with the usual result.
